Steel casting is a specialized form of casting involving various types of steel. Steel castings are used when cast irons cannot deliver enough strength or shock resistance.[1]
Examples of items that are steel castings include: hydroelectric turbine wheels, forging presses, gears, railroad truck frames, valve bodies, pump casings, mining machinery, marine equipment, Turbocharger Turbines and engine cylinder blocks.[1]
Steel castings are categorized into two general groups: carbon steels and alloy steels.[1]
